A 1970 gated community built a dozen years before it became a town
Duke Power sold 1,600 acres of former India Hook Hills land to Charlotte's Ervin Company in 1970, and Tega Cay was built that year as a private, gated Lake Wylie community, a full twelve years before residents voted to incorporate as a municipality on July 4, 1982. Every original Tega Cay house therefore predates the town government that now oversees it.
Red clay peninsula construction and today's basements
Before development, Tega Cay's peninsula was known as India Hook Hills for the red-clay spur of land jutting into the Catawba River, the same shrink-swell clay that now sits under every basement and crawlspace built there since 1970. Waterproofing work on Tega Cay's original 1970s housing stock has to account for both that peninsula clay and a half-century of lake-level changes.

What to tell us about a Tega Cay basement or crawlspace
Tell us whether the house dates to the original 1970s development or a later phase, how close it sits to the water, and where moisture is entering. Tega Cay's development history in distinct phases makes that timing detail more useful than it would be in an older courthouse town.
A peninsula community's drainage runs to the lake, not a river channel
Because Tega Cay sits on a peninsula rather than along a river channel, stormwater and groundwater on most lots ultimately drain toward Lake Wylie's shoreline rather than a single waterway. That layout affects how exterior drainage should be routed on peninsula lots compared with inland Rock Hill-area properties.
